Swap all emoji icons for Font Awesome (sidebar, homepage tiles, profile/chat/
list/settings/relay actions); add Roboto font + card elevation hover for a
Material feel. Replace the bottom 'Collapse' pill with a 3-line (fa-bars) toggle
in the sidebar header; remove the old collapse pill CSS/JS. Copy buttons toggle
FA check/copy via innerHTML. Plain text status (✓/✗) and back arrows kept.

New collapsible 'Relays' group in the sidebar (chat/file/message relay) that
expands to show its items and persists open state. Homepage gets a matching
Relays card group, and areas are now split by faded separator bars like the
sidebar. Relay pages are placeholder 'coming soon' stubs (/relays/{kind}).
